You should look VERY closely at the air flow requirements of the "tools" in that $54 play set from Sam's Club!!
Find your receipt and return those *toys* before it's too late!
BTW, I learned that the "hard way" about a year and a half ago. I bought a Coleman compressor and that "bargain" tool set at Sam's, got it home and immediately discovered that I should have left the whole kit and caboodle in the truck.
The compressor could only produce 5.4 CFM at 90PSI -- the impact wrench in that toy set required 11.5 CFM at 90PSI to produce a measly 200 ft lbs of reverse torque!
Well, DuH! Small wonder it wouldn't turn a loose nut! The other tools in that set were just as worthless!! Really crappy work ratings at enormous CFM requirements!!!
I ended up with a PC oiler compressor that delivers 6.8 CFM at 90PSI and a Ingersol Rand impact wrench that only needs 4.8CFM to produce 600 ft lbs of reverse torque. (The IR wrench cost darn near as much as the original Coleman compressor I returned.) Yes, I spent a lot more than I originally planned, but I "got it back" by avoiding repair shop labor by the time I finished the brake jobs on cars #1 and #2.
My other air tools now are almost all (carefully selected) from Harbor Freight's "professional" line. They work.
